Pentagon Documents Leak: What We Know So Far

Investigations are ongoing to determine the scope and source of leaked Pentagon documents that circulated online late last week.

Classified files detailing NATO military support for Kyiv, including evaluations of Ukraine's forces and its needs for launching a long-touted spring counteroffensive, surfaced on various social media sites ahead of the Easter weekend.

Many of the assessments were dated from the end of February and the beginning of March. The wide-ranging stock of documents covered Ukraine's capabilities, apparent United States surveillance and the Russian mercenary Wagner Group, which has been prolific throughout Russia's war in Ukraine.

"We are aware of the reports of social media posts and the department is reviewing the matter," Pentagon deputy press secretary Sabrina Singh said on Friday.
